I, the Spiritual Mentor of Beautiful Girls from All Over the World

Lin En, seemingly an ordinary Chinese language teacher at Sobu High School, harbors a secret. He's the sole occupant of the "Ten Thousand Worlds Safe House"! His "classroom" connects the world's most elite "problematic beauties"! At the outset, the safe house "picks up" a young girl who's recently lost her sister and is filled with hatred. Faced with her murderous intent, Lin En gives her a single assignment: "Go back and face your anger!" As Shinobu Kocho unleashes bloodshed across the Demon Slayer world with this "assignment," Lin En uses his first reward, "Emotion Perception," to precisely tap into Yukino Yukinoshita's loneliness! → Homura Akemi: From "Desperate Girl of Reincarnation" to "Demon God Who Controls Time and Causation," rewriting fate and subverting the universe! → Misaka Mikoto: From "Sinful Princess of Electricity" to "Thunder Empress on the Path to Absolute Power," piercing the divine realm with lightning and reshaping the order of Academy City! Of course, there's also the occasional everyday pretty girl... This world is truly wonderful, but sometimes it's just too much...
